Yeast vial possibly gone bad?

Noticed that my vial of WLP007 Dry English Ale yeast seemed "chunky". Didnít seem to run as easily in the vial from side to side (bad description, but all I could come up with). When I opened the vial, it seemed to almost have a sourish smell.

Has this vial gone bad? This is my first experience with this strain so Iím in the dark here
